AZLIN vs UNIPEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Azlin is a penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis.
Unipen (nafcillin) is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), blocking transpeptidation and autolysin inhibition.
1-2 grams intravenously every 4-6 hours; total daily dose up to 12 grams for serious infections.
500 mg to 2 g orally or intravenously every 4 to 6 hours; maximum 12 g/day IV for serious infections.

Terminal elimination half-life is approximately 1.0–1.5 hours in adults with normal renal function; prolonged to 3–5 hours in moderate renal impairment (CrCl 10–50 mL/min) and up to 10 hours in severe renal impairment (CrCl <10 mL/min).
0.5-1 hour in normal renal function; prolonged to 7-10 hours in anuria or severe renal impairment.
Renal excretion of unchanged drug (approximately 60-70% via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <10%.
Renal: 70-90% unchanged via tubular secretion and glomerular filtration; biliary: minor (<10%); fecal: minimal.
